We want to find the gradient and y-intercept of a given line.
The solutions are:
a) gradient = 3
b) y-intercept = 4
A general line written in slope-intercept form is:
y = a*x + b
Where a is the slope and b is the y-intercept.
The slope defines how the change in the variable y relates to the changes in the variable x, so the slope is also called the rate of change or gradient.
Thus, if we want to find the gradient, we must read the coefficient that multiplies the variable x, and the constant will be the y-intercept.
In the given line:
y = 3*x + 4
Comparing this with the general line, we can see that the gradient is 3 (the slope), and the y-intercept is 4.
